EVERYDAY SCIENCE

Detailed explanation-1: -Thalamus: The thalamus is the relay center of the brain. It receives afferent impulses from sensory receptors located throughout the body and processes the information for distribution to the appropriate cortical area. It is also responsible for regulating consciousness and sleep.

Detailed explanation-2: -The largest part of the brain, the cerebrum initiates and coordinates movement and regulates temperature. Other areas of the cerebrum enable speech, judgment, thinking and reasoning, problem-solving, emotions and learning. Other functions relate to vision, hearing, touch and other senses.

Detailed explanation-3: -(seh-REE-brum) The largest part of the brain. It is divided into two hemispheres, or halves, called the cerebral hemispheres. Areas within the cerebrum control muscle functions and also control speech, thought, emotions, reading, writing, and learning.

Detailed explanation-4: -The impulse crosses a synapse in the thalamus to nerve fibers that carry the impulse to the sensory cortex of the cerebrum (the area that receives and interprets information from sensory receptors). The sensory cortex perceives the impulse.

Detailed explanation-5: -Your cerebrum sends the signals to the muscles in your arms, and your cerebellum helps calculate and control your movements, so your hand goes right to the pencil without missing. Your cerebellum not only manages conscious thoughts, but also planning and actions.
